Further, the top of flange portion 51 still is equipped with spacing boss, and spacing boss and control knob looks adaptation can prevent that water or the soil infiltration of on the panel 60 is inside waterproof plug 50.

The height of the valve body is always about 55mm due to the height of the valve seat 10, the valve core 20 and the valve core 20, and the height of the cooker is over 60 mm. The reasons for this are as follows: 1. the existing valve seat 10 is generally provided with two air outlet pipes, the included angle of the two air outlet pipes is generally about 90 degrees, so that the distance between a central air hole 21 and an outer ring air hole 22 in a cavity of a valve core 20 is relatively short, the sealing area of the cavity of the valve core 20 on the horizontal plane is insufficient during ventilation, and the distance between the center and the outer ring air hole 22 needs to be increased longitudinally to increase the sealing area of the cavity of the valve core 20 and the valve core 20, so that the longitudinal distance between the outer ring air hole 22 and the central air hole 21 on the valve core 20 is relatively large, and the height of the valve core 20 is relatively high; 2. the central air hole 21 and the outer air hole 22 of the existing valve core 20 are partially overlapped, and the overlapped central air hole 21 or the outer air hole 22 adopts a vertical long-strip hole, which results in that the longitudinal distance and the longitudinal height of the central air hole 21 and the outer air hole 22 are larger, and the height of the valve body is increased in a non-type mode.

In the present embodiment, the valve seat 10 is provided with a second valve chamber 12 and a communication chamber 13; the second valve chamber 12 is provided with an electromagnetic valve 90 and communicated with the air inlet 14; the first valve cavity 11 is communicated with the second valve cavity 12 through a communicating cavity 13, and a deflector rod is arranged in the communicating cavity 13; one end of the deflector rod is positioned below the valve rod 40, and the other end of the deflector rod is connected with the electromagnetic valve 90; the valve rod 40 moves downwards, and the electromagnetic valve 90 can be controlled to be switched on or switched off through the deflector rod. The first valve cavity 11 and the second valve cavity 12 are arranged in a staggered mode and are communicated through a communication cavity 13 at the bottom; and a deflector rod structure, which makes the valve body thin and flat. The communicating chamber 13 is closed by a bottom cover 15, and the connecting structure of the shift lever, the valve rod 40 and the solenoid valve 90 is a direct application of the prior art and is not shown in the figure.

In this embodiment, the cavity of the valve core 20 is provided with a first air outlet 16 and a second air outlet 17 with an included angle of 145 ° to 180 °, and the heights of the first air outlet 16 and the second air outlet 17 are different; the valve core 20 is provided with a plurality of central air holes 21 and outer ring air holes 22 with different hole diameters; the central air hole 21 may communicate with the first air outlet 16, and the outer annular air hole 22 may communicate with the second air outlet 17, so that the valve body forms a multi-stage air supply.

The included angle between the first air outlet 16 and the second air outlet 17 is set between 145 degrees and 180 degrees, so that when the valve core 20 is ventilated at the central air hole 21 and the outer ring air hole 22 simultaneously, the included angle between the central air hole 21 and the outer ring air hole 22 is set between 145 degrees and 180 degrees, the distance and the angle between the central air hole 21 and the outer ring air hole 22 are increased from the horizontal direction, the sealing area is also increased, and the risk of air leakage and air leakage is reduced. Increasing the horizontal reverse distance provides a basis for reducing the distance in the longitudinal direction, so that the distance between the central air hole 21 and the outer annular air hole 22 in the longitudinal direction is reduced, the height of the valve core 20 is reduced, and an ultrathin valve body is formed.

It is to be understood that the present invention is not limited to the above-described embodiments, and that equivalent modifications and substitutions may be made by those skilled in the art without departing from the spirit of the present invention, and that such equivalent modifications and substitutions are to be included within the scope of the appended claims.
